3.2 SANITARY HOT WATER (S.H.W.)
Proceed to fill the 50-litre accumulator tank, opening the tap of the S.H.W. to draw out the air from the water
accumulator.
Once the water is flowing normally, shut off the tap and connect the S.H.W. by pushing the button. Select a
resistance temperature for the S.H.W. higher than the temperature shown on the S.H.W, display and check that the
consumption indicator of the S.H.W. resistances lights up.
Check that once the set point temperature has been reached, the consumption indicator goes off.
If at this moment a hot water tap is opened with a minimum flow, the consumption indicator will light up again
immediately thanks to the flow detection system. The set point will move 3°C higher than that selected during a
connection/disconnection cycle. This will supply more hot water as it will eliminate the dead time of the resistance
connection due to the lowering of the temperature in the tank.
4 LIMITATION OF THE MAXIMUM OUTPUT
It is possible to limit the maximum output of the boilers by selecting the combination required in the table
corresponding to each model.
The boiler output will never exceed the selected value.
The boiler will continue to modulate in heating mode on all the lower steps, adapting to the installation’s
consumption.
It is necessary to employ an external ambient thermostat or a chrono thermostat.
The output in S.H.W. on the CMX15 and CMX18 models is also limited to the maximum value of the corresponding
table.
To access the electronic card, disconnect the boiler from the mains and remove the front panel.
Removing the upper screws, tilt the control panel. Locate the main card.
Move the switches with a small screwdriver and make them coincide with the corresponding combination on the
tables for each boiler model.
Replace the front panel following the steps in reverse and connect the boiler to the mains.
IMPORTANT: Check immediately before activating the modulation system with a hook-on meter that the
consumption corresponds to the output selected.
On the CMX models, turn off the S.H.W. pressing the button to verify the heating consumption.

ATTENTION!
The switches are upside down.
